7 Survey and sampling strategy 7.1 Approaches Any reach within a river or stream is likely to contain a number of different substrata on which phytobenthos can grow, and some of these substrata may, in turn, be colonised by more than one type of phytobenthic growth form. In many cases, these growth forms will be visible to the naked eye, […]

1 Scope This European Standard specifies a gas chromatographic/mass spectrometric method for the determination of organochlorine pesticides (OC’s) and polychlorinated biphenyls (PCBs) in animal feeding stuffs and oil. The method is applicable to animal feeding stuffs with a water content up to about 20 wt% and oil/fatty samples containing residues of one or more of the following OC’s and PCBs […]

1 Scope This European Standard specifies a gas chromatographic method with electron capture detection (ECD) for the determination of organochlorine pesticides (OC’s) and polychlorinated biphenyls (PCBs) in animal feeding stuffs. The method is applicable to animal feeding stuffs with a water content up to about 20 wt% and oil/fatty samples containing residues of one or more of the following OC’s, […]

1 Scope This European Standard specifies a method for the determination of arsenic, cadmium, mercury and lead in foodstuffs by inductively coupled plasma mass spectrometry (ICP-MS). The collaborative study included foodstuffs such as carrots, fish homogenate, Mushrooms (CRM), graham flour, a simulated diet E (CRM), scampi, mussel and a Tort-2 CRM having an arsenic mass fraction ranging from 0,06 mg/kg […]

1 Scope This European Standard specifies a method for the determination of tin in foodstuffs and canned foods by flame and graphite furnace atomic absorption spectrometry (AAS) after pressurized digestion. The collaborative study included foodstuffs such as carrot puree, tomato puree, pineapple, mixed fruit, white wine, peach powder, tomato powder, powdered beans, powdered fruit yoghurt, fish powder, having mass fractions […]

1 Scope This European Standard specifies a procedure for the determination of appearance of ethanol by visual method. The method enables to determine colour and limpidity of ethanol. NOTE Automotive fuel standards require a fuel to be clear and bright, meaning absent of particles, respectively absent of haziness. For this document that requirement is combined into a limpidity requirement. 2 […]

1 Scope This standard specifies a test method for taking representative specimens, extraction of phthalates from the material and determination of phthalates by gas chromatography – mass spectrometry. This standard applies to textiles articles, where there is a possibility of the presence of some phthalates. 2 Terms and definitions For the purposes of this European Standard, the following terms and […]

1 Scope This European Standard defines general rules for the enumeration of probiotic lactobacilli in feed samples (additives, premixtures and feeding stuffs) that contain lactobacilli as a single bacterial component or in a mixture with other microorganisms. This standard is not applicable to mineral feeds, which are defined as complementary feeding stuffs composed mainly of minerals and containing at least […]

1 Scope This Standard is applicable to the determination of zearalenone in animal feed at concentrations from 30 µg/kg to 3 000 µg/kg. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies: […]

1 Scope This European Standard specifies a test method to determine the explosion points of flammable liquids in air. This European Standard applies to flammable liquids at atmospheric pressure and at temperatures in the range from – 50 °C to 300 °C. This European standard must not be applied to explosives or materials which, under the test conditions, are thermally […]
